These darned old computers

 Bingo ! I took both cases off and at first was dismayed since the "360k" has
a 30 pin edge connector and takes it's power from the host machine. Then I
saw that the TEAC drive had a 34 pin edge connector that was plugged into
the card with the 30 pin edge-c and a standard 5 1/4 floppy power plug.

 The 502 has a dummy faceplate for a second floppy and 2 data 34pin
connectors and 2 standard 3 1/2 floppy plug types as you say and a
whopping big PSU that must support 2 drives. There's one single square 2pin
plug which doesn't have any visible connector on either drive.
 The only mod needed would be to replace the small power with a large type.

 That's great. When you don't have a HD, 2 floppies sure makes things
easier. I recall with no pleasure spending hours doing the disk-change
mambo copying programs off magazine disks on my Atari ST.
